"tubes 6 are so formed that when air is blown go-rthereinto they will sound jflute'like notes,

and will hereinafter, be termed flutetubes whereas tubes/Z are so formed as to i sound a note similar to that of a violin, and

A constant suction of air is maintained throughout the channel jS, by means ot a main vacuum pump or feeder (not shown) through passagesto be herein;

after referred to. Mounted upon the up-- per wall of the channel8, near'oneof its ends is a valve'box' 9, and into which air is admitted from channel 8, through openings 10 and 11 formed in the upper-Wall thereof on opposite sides of a transverse partition 12 (see Fig. 12), Abent wire lever 13 journaled' in the end pieces of the valve box '9,

carries thereon within theivalve -box a valve 1 1, at a point directly above the opening 10, and has one of its ends formed with an extension 14 and which isnormally held so me raised position by means of a spring 15, secured at one'end to the; extension 14*, i and at its other endto a block 16, fastened to'the top of the valvebox 9: The top wallof I the box. 9 also carries a pneumatic 17, proJ' vided with an armil8, which arm is adapted to bear on the'extension 14? of the lever 13.

Formed Within the upper wall of the" valve box 9,- there is a port 19, whichleads to the interior of the pneumatic l7, and to which (i0 port is communicated a. tube 20, in turn leading to a T-block 21, fastened ,to the underside of the channels8, provided with 3 ports 21 and 22, the tube 20 "communicat ingwiththe port 21?. From port 22 a hose or tube 23, leads to a port 25 formed in the front wall (if a controlling ,valve' box 24c, fastened also to the ,underside of the channel 8, and'Whiclrport25 normally communllcates with the outside air; ,A vacuum is maintained within the controllingvalve box 2 1, through openings26 and 27 formed in,

Also leading from the interior oi the pn'eumatics '28 and 2 5 through the front wall' of the box 24 are ports 31, from which hose .32 lead to a '80 tracker-bar orother pneumatic playing device not shown), designed for. operating musical instruments by, admitting" air to passage for a period of time" corresponding 7 to that during ,rvliich a desired note i'sto be sounded. l7

A shifting lever. .33, having its ends bent at rightangles; is carried by thewfront Wall ofthe box 24;, and is adapted tobaveits lower inner end extend between thepneu- 9,0 matios 28 and 29, and its u per outer end carries, a valve block3 i'h'aving' its inner face provided with'a passageway 35, which is at all times in communication with a port 36, leading into the box 24, but. leaves: the f 7 port 25. open to theioutside airvexcept when the lower-end of the lever 33=isshifted by, V V the pneumatic 28 beinglinflated or' extended" and the pneumatic 29 collapsed, in Which event the valve block 34c-tvill extend over 1 00 both the sports 36 and 25'.

Secured to, the underside of theinain suction channel8, immediately below the valve box 9 is a, pneumatic regulator 38, pro

- vided with openings 39 and-40, which regise a ter with similar openings 11 and 42 respec- 1 tively formed in the under wall of the channel 8, and whichare in a'linement with the openings 10' and 11" above. Formed around i V the opening 39 is a valve seat 43, while the oppositeleafof thep'neumatic 38 carries a valve member 14 adapted to engagethe seat 43 and close the port39, in the event that the suction through the channel 8 andpneumatic 38 becomes too strong' However, to l preventthe closing of the'port39, except at 0 a predetermined time',-:the leaf of the-pneu-"K matic is provided with'a flat spring 45,-the

ed upon a chamber 108. The valve stem 106 is also provided with a valve 109, adapted to work within a chamber 110, having a port 111 leading to the interior of the valve box 99, anda port 112 leading to a horizontally municatesat each'end with the outside air;

The outsideair' is normally admitted to the,

interior of the pneumatic by meansof a passage 114,leading from the chamber 110. Leading from the chamber 10Sbeneath the diaphragm 107, there isa' port 115, to which is connected one end of a hose 116, the other end of which is connected to an intermediate valve box, which will be presently described.

Extending within the shelf 98 there is an arm 117,'the outer end of which isbent upwardly to form a handle 118 and the inner end of which is provided with a valve memher 119, adapted, when the handle 118, is] moved to one side, to raise the valve 119,

and close the passage 100, thereby cutting off communicationbetween the interior of the valve box 99, and the mainsuction cham; her 8, and consequently discontinumg' any farther sounding of the nstruments con.-

trolled by the valvev box 99.

As heretoforestated;Fig. 15 isa' section taken through the pneumatic for producing the base drum notes, its controlling valve and air ports or passage, and as an exact duplication of the valve and arrangement of ports above described, is provided within the valve box 99 for each of the pn'eumatics 102, it is not thought necessary to further the end of the valve box 99, adjacent to the controlling valve box 24, is a fourth valve and arrangement of air ports for control ling theg cymbal pneumatic 92, exactly the ports controlling the'base and kettle drum pneumatics, except that instead of the port" which corresponds to the port 114;, shown in Fig. 15, being connected directly to the pneumatic 92, it is connected thereto through the boss 96, heretofore mentioned.

Secured to the upper side of the suction channel 8, at a point suitably removed from the valve box 99, there is an intermediate valve box 120, the interior of Which is connected with thesuction channel 8, through suitable ports 121,pand consequently air Will be constantly exhausted from the interior of the valve box 120, by the suction of air diameter than that of the openings 1310, the

Also arranged. Within is for 'the purpose of 'permitting' ports or passages to lead from the valves to either p thefront or back of the valve box in parallel relation, but without interfering with one) another. The five valves are identical in structure, each comprising a stem 127 fastened at its lower end to afdiaphragm 128,

monntedover a chamber" 129 ,and extending upwardly throughf openings 1130, formed through the top boardof the valve box, and 7 being guided at their extreme upper ends by acover 131. Fixed tothe 'valve'stems 1 127, at "points above and below the top board of the valve box areva-1ves182, larger in distance between the valves being slightly greater than the "thickness of the said top board or" thevalve box,whereby when one ofthevalves is seated overthe adj'acentfend' of theopening 130, the othervalve will rest a slight distance away from the other end.

of the opening so that no matter whether the valve stems1127are raised or lowered, only oneend of the openings1 30, Will'be closed, the other end remaining open. 1 As most clearly shown in Figs, 23and 2 1, the cover 131is raised above the'top board of the valve box 120, so'as to form a space 133 therebetween, and Which space opens'to' the outer air at both ends of the valve box. E11 1 tering the bottom board of the valve, box 1.20, from the rear side thereof are ports 1 13. 1, one leading to .eachi'of' the chambers 129,below the diaphragm 128, and thence to the front wall ofthe valvejbox, at which point each port 134: has inserted thereinla bleed 135. QThes'e bleeds 135 communicate with a groove 136 formed1in ablocklBT, secured to the front Wall of the valve box its groove 136opposite the bleeds 135, As shown in Fig. 22 the groove 136 is con- 'nected' with the interior of the valve box and consequently with theexhaust by means of the passages 136 shown-by dotted I lines.
